The Nightside Raiders were a pirate organization in the Unknown Regions, plaguing the Tetrarchy of Mezlagob from at least 50 BBY until the second century after the Battle of Yavin. Led by a pirate with the rank of Captain-General, the Raiders fielded a small fleet of modified freighters, corvettes, and other large starships and small capital ships. They often preyed on civilian convoys in the Mezlag and Vall`to Sectors, occasionally even engaging government ships when gathered in sufficient force.
